Don’t wash your dishes before loging on to the computer

This morning I washed my dished (manually in a kitchen sink) and afterwards (with dry hands) I tried to log on to my computer using the finger print scanner. My thumb did not work anymore. Looking closer at my thumb it seemed clear that this looked temporarily different as it was in the water for 10 minutes. A few minutes later the thumb is back to normal, but I already logged using a password. What do I learn from this – If I will do a ubicomp project in the kitchen (similar to things we did in Munich) I will not use finger print scanners for authentication.
